It looks to me that your Emacs is now using old GPG 1.4 and not GPG 2.x
version. Emacs has some magic code to choose which one to use but the
logic is unknown to me. There is also variable epg-gpg-program.

GPG 1.4 will connect to agent if ~/.gnupg/gpg.conf file has this line:


GPG 2.x don't need that option because they always connect to the agent.
